One day, Isuzu is finished with her intense swimming practice for her Swimming Olympic Tournament next week and decides to go on an arcade called "Game Center" to make her feel relax.

Well, time to make me feel like myself at home...

She plays Street Fighter, where she always won constantly...

Man, swimming and fighting games are indeed the two things I lived for...!

As she puts her hands behind her head to relax herself, she noticed someone stalking her...

A stalker...? Really...?

She sighed in annoyance before standing up with her knuckles cracked and walked away to know who that is...

Whoever you are, you better face my fist...!

She was stunned after seeing the person who stalked her, but it happened to be you...

Wait, um... who are you?
